Estudio geotécnico in Rociana del Condado

In Rociana del Condado, the dominant bedrock is mainly made up of limestones, dolomites and marbles, accompanied in smaller proportions by sandstones and conglomerates. These materials generally provide a high bearing capacity, making them suitable for direct and shallow foundations, provided that the absence of relevant discontinuities is confirmed. The local presence of flysch or layers of sandstone may require a local assessment due to possible variations in strength and low permeability, which affects drainage and the ground’s behaviour.

The recorded seismicity in the municipality is very low, with only 2 events over 30 years and a maximum magnitude of 2.7, so seismic action is considered of little significance in structural design. The risk of expansivity due to clays is low, since these occur in a non-expansive or dispersed form within a non-clayey matrix, minimising the likelihood of volumetric movements. The main geotechnical constraint will be the detailed characterisation of lithological heterogeneity, given that the mechanical behaviour of the carbonate rocks is the key factor to be defined in the geotechnical study.
